Types ¶
type Controller ¶
Controller is the core-side implementation of extension.BackupController. It projects backup-eligible instances, reports last-success times, and enqueues backup jobs over the same path as the HTTP POST /backups handler.
func (*Controller) EnqueueBackup ¶
func (c *Controller) EnqueueBackup(ctx context.Context, host, template, slug string) (string, error)
EnqueueBackup enqueues a backup job for one instance, deduping against any backup already queued/running/reconciling for the same instance.
func (*Controller) LastBackupAt ¶
func (c *Controller) LastBackupAt(ctx context.Context, host, template, slug string) (time.Time, error)
LastBackupAt returns the finish time of the newest complete backup for an instance, or the zero time if none exists. ListBackups is newest-first, so the first complete row wins.
func (*Controller) ListBackupInstances ¶
func (c *Controller) ListBackupInstances(ctx context.Context) ([]extension.BackupInstance, error)
ListBackupInstances walks every known host, lists its live instances, and returns those whose template declares at least one backup-marked volume. A per-host listing failure is logged and skipped rather than aborting the whole sweep, so one unreachable host doesn't starve backups on the others.
type Service ¶
type Service interface {
Hosts() []config.Host
ListAllInstances(ctx context.Context, host string) ([]instance.Observed, error)
GetTemplate(ctx context.Context, id string) (store.Template, error)
ListBackups(ctx context.Context, host, template, slug string, limit int) ([]store.Backup, error)
CheckBackupable(ctx context.Context, host, template, slug string) error
}
Service is the slice of *instance.Service the controller needs. Declaring it as an interface keeps the controller unit-testable with a fake.
